BACKGROUND

At present, Internet technology has been widely used on a global scale. People are increasingly participating in various activities over Internet. Network media have also become a non-negligible emerging medium which has been paid more attention.

As compared with traditional a media such as newspaper, radio broadcast and television, network media has various features such as a low entry cost, massive scale of information, rapid information distributing and spreading, a large number of participants, and enhanced real-time interaction. Since the cost for publishing network information is extremely low, there is no clear boundary among providers, spreaders, and readers of the information. Information network has become a “virtual society” with very distinct social group characteristics. Especially when an event occurs, people will participate in discussions the event by means of news commentary, community forums, microblog or the like. Through corresponding analysis on public opinion, people's concern and other important information may be obtained.

A critical object of the analysis on the public opinion is to analyze and determine the audience of the event. An important issue to be solved urgently is how to accurately determine the audience of an event through the analysis on the massive data generated on the network.

DETAILED DESCRIPTION

Hereinafter, only some exemplary embodiments are simply described. As can be recognized by those skilled in the art, the described embodiments may be modified in various different ways without departing from the spirit or scope of the present disclosure. Accordingly, the drawings and the description should be considered as illustrative in nature instead of being restrictive.

FIG. 1 shows a flowchart of a text analyzing method 100 according to a first embodiment of the present disclosure. As shown in FIG. 1, the text analyzing method 100 includes steps S110 to S130.

In Step S110, a target text and a first set of texts to be compared are acquired. The first set of texts to be compared includes at least one text to be compared, and each of the texts to be compared is a search text entered by a user in one search.

In a preferred embodiment of the present disclosure, the target text is description of an event in the form of text, preferably a news headline, such as “Jay ZHOU's concert in Beijing” or “Apple released iPhone 8”. Hereinafter, by taking the text “Jay ZHOU's concert in Beijing” as the target text, the text analyzing method provided by the embodiment of the present disclosure is described in detail.

In an embodiment of the present disclosure, the text to be compared is a search text entered by the user in one search. It is understood that the text analyzing method provided by the embodiment of the present disclosure may be performed repeatedly. The number of texts to be compared acquired when the method is performed at this time is different from that acquired when the method is performed for the next time. This is because an additional search may be conducted during the time interval between this time and the next time.

In addition, in a case that the target text is a news headline, it is necessary to consider the timeliness of the news in order to ensure the accuracy of the analyzing result. It is understood that the at least one text to be compared acquired in step S110 may be search data entered by the user within a preset time period. In particular, the preset time period may be 24 hours, 48 hours, or even one week, depending on the content of the target text, which is not specifically limited herein.

In step S120: a text similarity between the text to be compared and the target text is calculated based on a semantic similarity algorithm for short text, and a text to be compared with a text similarity higher than a first threshold is determined as an object to be analyzed.

Currently, the similarity between two texts is generally calculated by firstly splitting the text and selecting a keyword. In addition, in an embodiment of the present disclosure, the target text and the text to be compared are short in length, and only relates to one topic. In view of this, in an embodiment of the present disclosure, similarity analysis is performed by a semantic similarity algorithm for short text, so as to determine the object to be analyzed more accurately.

For example, literally, “Beijing” and “capital” are not similar, but in Chinese, they have the same meaning. In addition, due to differences in languages, texts that are seemingly not similar to each other at all may also express the same meaning. For example, “Xingchi ZHOU” and “Stephen Chow” refer to the same person, and “Yinyue” and “music” have the same meaning. In addition, words sometimes have special correlation with each other. For example, for “Jay ZHOU's concert in Bird's Nest” and “Jay ZHOU's concert in Beijing”, the keywords “Bird's Nest” and “Beijing” seem to have no correlation with each other. However, there is a correlation between the two searches associated to the two texts since the Bird's Nest is located in Beijing and is often used for holding a concert.

In this case, if only the characters in the text are compared, a lot of information will be missed. Therefore, in the embodiments of the present disclosure, the semantic similarity algorithm for short text is applied to analyze a text.

As shown in FIG. 2, in an embodiment of the present disclosure, step S120 may include the following steps S121 to S125.

In step S121, a first similarity between the text to be compared and the target text is calculated by Elasticsearch.

ElasticSearch is a Lucene-based search server. It provides a distributed multi-user-enabled full-text search engine based on a RESTful web interface. Elasticsearch was developed in Java and released as open source codes under the Apache license terms, and is an enterprise search engine that is currently prevailing. It is designed for cloud computing, and has advantages such as performing a search in real time, stable, reliable, efficient, and easy to install and use.

In this embodiment, the first similarity is calculated by using a similarity algorithm that is built-in in the Elasticsearch. Lucene (a full-text search engine) is used in a bottom layer of the ElasticSearch, and score calculation in Lucene is performed by integrating a Boolean model, TF-IDF, and a vector space model. In the Elasticsearch, a default tf/idf model, and three similarity models of bm25, drf and ib are provided. In this embodiment, any one or more of the above models may be applied as required to calculate the first similarity.

In step S122, at least one text to be compared with a first similarity higher than a second threshold is selected from the first set of texts to be compared, as a second set of texts to be compared.

In this embodiment, the Elasticsearch is used for preliminary selecting, for preliminarily filtering the texts to be compared, thereby further improving the accuracy of object determining.

In step S123, the target text is word-segmented to obtain at least one keyword, each keyword is vectored with a word2vec model to obtain at least one vector, and the at least one vector is summed to obtain a first summing result.

In step S124, for each text in the second set of texts to be compared, the text is word-segmented to obtain at least one text keyword, each text keyword is vectored with a word2vec model to obtain at least one vector for the text, and the at least one vector for the text is summed to obtain a second summing result.

It is well known that a character is the smallest unit in Chinese language, but in actual use, the smallest language unit that may be used independently is a Chinese word. A Chinese sentence, which is a character string used in a computer, is often difficult to be understood by a machine. Therefore, in practical applications, the key technology for Chinese language processing is word segmentation. On the basis of word segmentation, upper layer applications may be performed, such as syntactic analysis, machine translation, and semantic understanding.

Therefore, in an embodiment of the present disclosure, in order to perform the similarity calculation, it is necessary to word-segment the target text and each text in the second set of texts to be compared. It should be noted that for word segmentation, a punctuation mark, a special symbol (such as underline), or a stop word may be deleted from the text firstly, in order to obtain a more accurate result. A stop word refers to a certain character or word that is automatically filtered out before or after processing natural language data (or text) in information search so as to save storage space and improve search efficiency. Steps S123 and S124 may be performed by any existing means, which is not specifically limited herein.

The word2vec model is essentially a model of matrix decomposition. Briefly speaking, a matrix herein describes a set of a word and a word in the context thereof. The matrix is decomposed and only a vector corresponding to each word in an implicit space are used. For a short text, the vectors corresponding to all the words in the text may be summed directly and linearly to use in a training classifier of a text feature, so as to perform the text analysis.

In step S125, the text similarity between a text in the second set of texts to be compared and the target text is calculated based on the first summing result that the second summing result, and a text to be compared with the text similarity higher than the first threshold is determined as the object to be analyzed.

In a preferred embodiment of the present disclosure, the text similarity is a cosine similarity. The cosine similarity is used to evaluate the similarity of two vectors by calculating the cosine value of the angle between the two vectors. However, it is understood that the first similarity in the embodiments of the present disclosure may also be of another type, and may be selected as actually required, which is not specifically limited herein.

In particular, the cosine similarity may be calculated using the following formula:

${{sim}\left( {X,Y} \right)} = {{\cos \; \theta} = \frac{\overset{\rightarrow}{x} \cdot \overset{\rightarrow}{y}}{{x} \cdot {y}}}$

wherein x and y is a vector respectively, and sim (X, Y) is a similarity between vectors x and y.

In step S125, a further filtering may be performed on the texts to be compared, so that the determined object to be analyzed is more accurate and targeted.

In step S130, a target user entering the object to be analyzed; is determined; and the target user is statistically analyzed based on at least one attribute of the target user, to generate and output an analyzing result of the target text respective to the target user.

After determining the object to be analyzed in step S120, the target user entering the object to be analyzed is analyzed to obtain the audience of the target text.

In this embodiment, the target user is a user a user who enters a search text with a similarity higher than the first threshold with the target text. The statistical analysis is performed based on at least one attribute of the target user.

In a preferred embodiment of the present disclosure, the at least one attribute may include gender, age, region, career, etc., although it is conceivable that the user also has other attributes which are not be listed herein. Any feature that may be used to divide users into different groups may be referred to as an attribute, such as the education background of a user.

In this embodiment, the attribute may be obtained by any existing technology, such as a common gripping tool, which is not specifically limited herein. The statistical analysis on the target user is based on the statistics of the number of users for each attribute, and thereby a statistical result is generated and output.

It is understood that the at least one attribute may be selected as actually required. For example, for an entertainment-related event, the user's age, gender, and other related attributes may be selected; and for a politics-related event, the user's education background, age, and other related attributes may be selected. The selection of attributes is also related to the reliability of the final statistical result.

With the above methods, the search data related to the target text may be analyzed, and then the statistical result of the corresponding user, which is the audience of the target text, may be acquired for providing a reference for public opinion analysis.

In an embodiment of the present disclosure, as shown in FIG. 3, step S130 may include the following steps S131 to S133.

In step S131, an attribute of the target user entering the object to be analyzed is acquired.

This step may be implemented by any one of the existing technologies, which is not specifically limited herein.

In step S132, at least one attribute with a confidence level higher than a third threshold is selected from a preset attribute library.

In an embodiment of the present disclosure, the preset library may be any attribute database that includes a user ID, a name of the user attribute, a confidence level of each attribute, and other information. The information in the library, particularly the confidence level, may be acquired using any one of the existing technologies, which is not specifically limited herein.

It is understood that the acquired confidence level of the user attributes are not necessarily identical with each other. The higher the confidence level is, the more reliable and accurate the attribute will be. Therefore, it is necessary to filter the attributes. In a preferred embodiment of the present disclosure, the threshold of confidence level may be 80, although other values may also be used, depending on the desired accuracy of the result.

For example, the information of the user in the preset library is: gender: female, confidence level: 90; age: 25-34, confidence level: 98; city: Guangzhou; confidence level: 60.

In the above information, gender, age and city are respectively a name of a user attribute, and the confidence levels of these attributes are not identical. Since the attribute “city” of the user has a confidence level of 60, which is lower than the third threshold 80, it cannot be used for statistical analysis on audiences of an event.

In step S133, the target user entering the object to be analyzed is statistically analyzed based on the at least one attribute, to generate and output the analyzing result respective to the target user.

With the above method, the attributes used in the statistical analysis may be filtered, and only an attributes with a high confidence level is used for the statistically analysis. The generated result is more accurate and the user's description is more credible.

In particular, in the embodiments of the present disclosure, the first, second and third thresholds may be set as actually required, which are not specifically limited herein.

The text analyzing method provided by the embodiments of the present disclosure will now be described in detail in a specific example. In this specific example, the target text is “Jay ZHOU's concert in Beijing”.

Firstly, the first analysis on the audience of the corresponding event is to obtain search data in a certain time period, for example, 48 hours. Secondly, the target text and the acquired search data are analyzed with the semantic similarity algorithm for short text to obtain the text to be compared with a similarity higher than the first threshold, and this text is determined as an object to be analyzed. For example, in this example, the text like “Zhou Jielun concert in the capital” and “Jay Zhou's concert in the capital” will be considered as an object to be analyzed. Afterwards, the audience of the event may be updated in an incremental updating manner, i.e. the user analyzing based on text analysis provided by the embodiments of the present disclosure is repeated at a preset interval so that the generated result is updated and the result is more accurate.

In this example, since Jay Zhou holds a concert in Beijing, the age and geographical location may be selected as the attributes for analyzing the target user. For convenience of performing statistics, the attribute “age” may be divided into age groups for statistics, such as, 10-15, 15-20 . . . .

The generated statistical result may be output in a more intuitive way, for example, in pie charts, bar charts, etc., and the statistical result may be directly displayed on a display device so that the statistical result is clear at a glance, and the audience of this event “Jay Zhou's concert in Beijing” may be clearly observed.
